[CLAUDE] App: menu tree inheritance mo rong Pe_* + PeWf_*

GetMyMenuTreeQuery truoc chi inherit Contracts (Ct_*) va Workflows
(Wf_*). Extend 2 root moi PurchaseEvaluations (Pe_*) + PeWorkflows
(PeWf_*) de admin co PurchaseEvaluations.Read auto thay 2 group Pe_* +
6 leaf (Danh sach/Thao tac/Duyet x 2 type) + 2 PeWf_* leaf admin designer
UI, khong can add per-subitem permission row.

Verify bug: /menus/me cho admin hien chi root 'PurchaseEvaluations'
+ 'PeWorkflows' nhung khong co Pe_DuyetNcc group / Pe_DuyetNccPhuongAn
group children du DB co 12 row (sqlcmd confirm). Root cause: hardcoded
2 inherit roots trong BuildChildren switch.

Fix: expand switch cover 4 inherit roots. Propagate nextInherit xuong
tat ca descendants.
